I'm new to the site but not to the AR 15. I have built 3 rifles so far and rebuilt my first rifle a year ago. Now to my question:
I have ended up the owner of a 20" SS bull barrel (rifle length gas system) with a gas port of .143". The bore is in good shape but I feel the gas port being so large will make the rifle expierience cycling problems.
So should I scrap it? Or is there a way to fix it without having to spend alot of money that could go toward a different barrel that is good. Thanks for the advise.
